* The air intake pipe can be increased to 2.5 metres if the exhaust bend is
eliminated, 2 metres if the air intake bend is eliminated, and 4.5 metres
eliminating both bends.

• Extension pipes and elbows push-fittings. To
install push-fitting extensions with other ele-
ments of the flue extraction elements assembly,
proceed as follows: engage the pipe or elbow
with the male side (smooth) in the female
section (with lip seal) up to the stop on the
previously installed element. This will ensure
sealing efficiency of the coupling.
• Installation clearances. Figure 1-22 gives the
min. installation space dimensions of the
Ø 80/80 separator terminal kit in limited
conditions.
• Figure 1-23 shows the configuration with ver-
tical exhaust and horizontal intake.
• Extensions for the separator kit Ø 80/80. The
max. vertical straight length (without bends)
that can be used for Ø 80 intake and exhaust
pipes is 41 metres of which 40 intake and 1
exhaust. The total length corresponds to a
resistance factor of 100. The total usable length
obtained by adding the length of the intake and
exhaust pipes Ø 80, must not exceed the values
stated in the following table. If mixed accesso-
ries
or components are used
(e.g. changing from
a separator Ø 80/80 to a concentric pipe), the
maximum extension can be calculated by using
a resistance factor for each component or the
equivalent length
. The sum of these resistance
factors must not exceed 100.
• Temperature loss in flue ducts. To prevent
problems of flue gas condensate in the exhaust
pipe Ø 80, due to flue gas cooling through the
wall,
the length of the pipe must be limited to
just 5 m.
(Fig. 1-25). If longer distances must
be covered, use Ø 80 pipes with insulation (see
insulated separator kit Ø 80/80 chapter).
N.B.:
when installing the Ø 80 ducts, a section
clamp with pin must be installed every 3 metres.
The kit includes:
N°1 - Exhaust gasket (1)
N°1 - Flange seal (2)
N°1 - Female intake flange (3)
N°1 - Female exhaust flange (4)
N°2 - 90° bend Ø 80 (5)
N°1 - Intake terminal Ø 80 (6)
N°2 - Internal wall sealing plates (7)
N°1 - External wall sealing plate (8)
N°1 - Exhaust pipe Ø 80 (9)
Important:
if installation requires extending the flue fittings up to the exhaust a length that exceeds the 12 m recommended, it is necessary to properly
consider the possibility that condensation may form inside the duct and therefore Immergas “Serie Blu” insulated flue fittings, or other flue fittings with
similar characteristics, should be used.
